Computer boots to text when on battery power

[Scott Thatcher]

Binary package hint: plymouth

When booting while my laptop is plugged in, I get the graphical splash screen, but when the laptop is on battery power, I get the text screen. That's the text screen that resembles the graphical one, with "Ubuntu 10.4" over four dots that change color. This is a very reproducible issue, with the laptop always coming up with a graphical splash while plugged in, and with it coming up in text mode at least 9 times out of 10 when on battery power.

After the text mode boot, the computer ends up at a black screen. To get to the graphical login screen, I have to do something like CTRL-ALT-F1 to get to a text login, then follow that with ALT-F7 to get to the graphical login screen.

The computer might eventually get to the graphical login on its own, but it takes at least longer than a minute to do so, and I've only been able to wait long enough for it to happen once.

Please let me know if I can provide any additional information.

I should add a couple more things.

I initially assumed that it might have something to do with the processor running slower while in battery power and something not being detected or run in time, so the default going to text mode. However, the behavior was unchanged when I changed BIOS settings to set the computer to run at full speed even on battery power. I don't know how soon the OS takes over control of power-saving, but I thought I'd add that bit of information.

Also, I can't directly hit ALT-F7 or CTRL-ALT-F7 to get to the graphical login. I do have to switch away to another screen first.

Hello!
I have amd64 Ubuntu 10.04 running on my
Hewlett-Packard HP Pavilion tx1000 Notebook PC

while it on battery power after loading splashscreen monitor turns black. And i should for examlpe reopen the display, or press Ctrl+Alt+F1 > Ctrl+Alt+F7 to get it back.

Also when i press Ctrl+Alt+F1 anytime while I'm on nvidia restricted driver a console has low resolution and shakes..

All,

I have the same issue with my HP tm 2000 with nivida 6150

This is what I found:
You will get this behavior if you upgrade the nvidia driver either from ubuntu "restricted drivers" or by downloading the latest driver from nvidia.
I reinstalled my laptop and kept the driver that came with the installation and the issue disappeared. I am able to reboot and get to gnome while on battary. So it has to do with upgrading the video driver and something with power safe .. "just a guess".

Also, while upgrading the driver with the latest from nvidia I get:

THE DISTRIBUTION-PROVIDED PRE-INSTALL SCRIPT FAILED.
UNABLE TO LOAD nvidia.ko the kernel module
which is mentionaed in this link:
